lesson
Choose one of two paths
1 · Learn
Selection lets a program choose actions based on a condition. In 'if answer is 8, show correct; else, show try again', exactly one branch is chosen each time that decision is evaluated.
Put actions in the intended branch. A command after the if/else runs afterwards regardless of which branch was chosen, unless the program has another control that stops it.
2 · Worked example
If the submitted answer is 6, the model shows try again. It should not show correct just because the user clicked a button.
3 · Your turn
In 'if number > 5, show large; else, show small', what is shown for number 5?
Check your answer
Small, because 5 is not greater than 5. The label is only part of this model; choose wording appropriate to a real task.
4 · Apply your learning
Implement a two-branch decision in an approved block tool. Test both branches and the boundary value.
Adult guidance and safety
Use adult-approved offline or school-managed tools, invented data and original media. Keep projects private unless sharing is explicitly approved. Paper traces support, but do not replace, practical programming and saved digital work. No real passwords or personal records belong in these exercises.
Open your writing and drawing pad
Write, draw or show your working. Use a mouse, pen or finger. This pad is not a submitted answer.
Not saved to your account. Download your drawing as PNG and your typed notes as TXT before leaving or refreshing. They are separate files. Do not enter private information.
Open a picture saved on this device to draw on it again. Opening replaces the drawing, but Undo can restore it. PNG only, up to 4 MB and 4096 × 4096 pixels. The picture stays in this browser; it is not uploaded. Paper lines in a saved picture become part of that picture.
Clear the drawing? Your typed notes will stay. You can undo this action.
Your pad is empty.
Open a UTF-8 TXT file from this device, up to 40 KB and 10,000 characters. It stays in this browser. Opening can be undone until you type again. Downloads keep a new copy; they do not change the file you opened.
Replace the notes on this page with the opened file? Download the current notes first if you want to keep them.
Typed notes are not submitted answers.
Check a calculation · Year 5 onward
Use this only when your teacher or adult allows a calculator for the task. Show your thinking first. It does not replace mental or written arithmetic and does not mark your lesson answer.
